WILLIAM H. SLAYBAUGI-I, OF EAST TOLEDO, OHIO, ASSIGNOR OF THREE-EIGHTHS TO WILLIAM T. DAVIES, 0F TOLEDO, OHIO.

DRIER FOR GRAIN OR THE LIKE.

To all whom it may concern:

Be it known that I, VILLIAM H. SLAY- BAUGH, a citizen of the United States, and a resident of East Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Drier for Grain or the Like; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make Aand use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to driers for grain, corn or the like, but is not restricted to such use as it can be used in any connection for which it may be appropriate as for screening purposes or the like.

The object of my invention is the provision of an improved apparatus of this class, which is simple and eiiicient in its construction, economical of manufacture, and capable of being easily and quickly set up or knocked down, whereby to enhance its practicability and commercial value.

The invent-ion is fully described in the following specification, and while in its broader aspect it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,-

Figure 1 is a central vertical section of the apparatus embodying the invention. Fig. 2 is an enlarged section on the line m in Fig. 1. Fig. 3 is a side elevation of the machine. Fig. 4 is a cross-section on the line g/ y in Fig. 3, with al portion broken away, and Fig. 5 is a top plan view thereof.

Referring to the drawings, 1 designates the housing or casing of an apparatus comprising my invention, and is shown, in the present instance, as comprising a plurality of rectangular sections, preferably of sheetmetal, which are placed edge to edge one over the other to build the apparatus to any desired height, the abutting edges of the sections being secured together by bands 2 which are bolted to the associated edges of the sections which they lap. This provides a housing structure which can be easily built up or knocked down, as desired.

Located within the housing 2 in superimposed order are a plurality of shaker-frames specification of Letters Patent.

3, which have their bottoms adapted for the passage of air therethrough, being screened, perforated or otherwise suitably formed for such purpose. Alternate ones of the shakerframes 3 are oppositely inclined, as indicated, and the elevated end of each frameprojects beyond the adjacent or lower end of the frame next above to adapt it to catch matter falling therefrom. It is thus apparent that matter will pass in one direction down one frame, from which it falls to the elevated end of the frame next below and passes down it in the opposite direction, and so on to the bottom of the apparatus. The elevated end of each frame, except in the present instance the top one, is provided with an upwardly and outwardly project-ing flange 4 which is carried by the frame and continually held in contact with the adjacent side of the housing 1 during a reciprocatory or shaking movement of the associated frame by spring fingers 5, as shown, thus preventing matter falling from one frame to another from passing between the housing side and t-he elevated end of a frame.

Each frame 3 is suspended at the sides thereof from bars 6 by pivotal links 7 which connect the bars and frame adjacent their ends. The bars 6 are preferably of angle iron, as best shown in Fig. 2, and have their horizontal flanges projecting inwardly from the housing sides and resting upon the downwardly and inwardly turned ends of fulcrum pins 8 which project from t-he adjacent housing sides centrally of the bars 6. The frames are arranged and operated in pairs and between the spaced ends of each pair transversely thereof are located the rock-shafts 9 and 10, which are suitably journaled in the housing sides and project at one end without such sides, as shown in Fig. 3. The shaft 9 carries a vertically disposed cross-arm 11, the opposite ends of which are connected by

links

12, 12 to the adjacent ends of the associated bars 6, as best shown in Fig. 1, thus adapting a rocking of the shaft 9 to effect a vertical rocking of the bars 6 and attached frames 3 toward and away from each other. The rock-shaft 10 has vertically disposed cross-arms 111 mounted thereon adjacent the housing sides, the ends of which are connected by

links

15, 15 to the respective upper and lower frames 3 of the associated set adjacent their centers, as indicated, thus causing a rocking of the shafts 10 to impart a longitudinal reciprocatory movement to each of the at- 5 tached frames 3. The connecting of the rock-shafts to the frames 3 and bars 6 in this manner causes them to Yhave vertical oscillatory movements toward and away from leach other and simultaneous horizontal shaking or reciprocatory movements in reverse directions, thus creating a balanced action to eliminate jar from the apparatus.

i The shafts 10 are provided Withoutone side of the housing 1 with horizontallyprojecting crank-arms 16, which are all connected together by a vertical bar 17 having pins 18 working in horizontal slots 19 in the arm ends, as shown in Fig. 3. The bar 17 also attaches to the outer ends of rock- 20 arms 2O projecting horizontally from the stud 24 projecting from the housing side.

The horizontal arm of the lever 23 is connected by a bar 25 'to an eccentric strap 2G which is mounted on an eccentric 27 carried byv a shaft 28 on top of the housing 1. The shaft 28 is shown, in the present instance, as carrying a stepped pulley 29 which is connected 'by a belt 3() to a stepped pulley 31 on a shaft 32 mounted on the top of the 35 housing adjacent one side thereof. The shaft 32 carries a drive pulley 33 which may be driven in any suit-able manner. It is apparent .that all of the rock-shafts 9 and 10 are operated in unison froml a single eccentric 27 and that such eccentric may be driven at any desiredV speed by changing the belt on the

stepped pulleys

29 and 31.

Grain or other matter is delivered to the elevated end of the upper shaker frame 3 through a hopper 34 into which it may be deposited by a chute 35 or in any other suitable manner.

Located within the apparatus between the shaker frames 3 are a plurality of sets of steam coils 36 which are shown as connecting with Veach other without the sides of the housing 1 by pipes 37 and the lower one as having Vconnection with a supply pipe 38. The purpose of the steam pipes 36 is to heatair passing through the apparatus to facilitate a drying of matter in its passage over the shakers 3.

A circulation is created within the housing 1 by a fan 39 which is carried within a conduit or casing 40 at the top of the housing by a shaft 41. The fan is driven by a i belt 42 connect-ing the pulley 43 on its shaft with the pulley 44 on the shaft 32. (See Fig. 5.) The conduit 40 has communication with the interior of the housing through the top thereof and upon a rotation of the fan, air is caused to enter the housing through openings 45 at the lower end thereof and pass upwardly through the housing and perforated bottoms of the frames 3, being heated by radiant heat from the steam pipes 36 as it ascends, and leaves the housing through the conduit 40.

Grain or other matter, after leaving the lower shaker frame 3, drops upon an inclined trough 4G by which it is delivered from the housing through an opening 47 in one side thereof.

48 designates angle-iron bars which are secured vertically to the sides of the housing and serve to strengthen such sides, unite the sections thereof, and to hold the fulcrum pins 8 supporting the bars 6.

In the operation of my improved apparatus, grain, corn or other matter to be dried is deposited in the hopper 34 by which it is delivered to the upper shaker frame 3. The matter traverses the length of the successive frames, falling from one to the other in its progress and finally being delivered in a dried state from the apparatus by the delivery trough 4G. The matter is agitated and its progress over the respective frames 3 facilitated by the compound vertical oscillatory and horizontal reciprocatory shaking movements which are communicated to the frames 3 by their connection with the rockshafts 9 and 10, which are in turn rocked by suitable connection with the eccentric 27, as above described. As the grain or other matter when in a wet or damp state is more. sluggish in its movements and therefore does noty move as readily as when in a drystate, each frame 3 is preferably inclined slightly more than the one next below, as shown in Fig. 1. As the grain passes downwardly across the shaker frames and from one to another thereof, the hot air passing upwardly through the interior of the housing and the perforated bottoms of the frames causes the matter to be thoroughly dried before leaving the housing. lVhile only four shaker frames are shown, it is apparent that any desired number of the same may be used.

I wish it understood that my invention is not limited to any specific construction or arrangement of the parts except in so far as such limitations yare specified in the claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is,
